634 cGy, p = 0.041). For the gross tumor volume of lymph nodes (GTVnd), 44 patients and 144 patients were classified as the enlargement group and the control group, respectively. After matching, 39 sub-pairs of 78 patients were generated in the post-PSM cohort. The GTVnd enlargement group exhibited no significant disadvantages in all of the dosimetric parameters. Univariate and multivariate analyses showed that the enlargement of GTVnx and the enlargement of GTVnd were not independently associated with any of the dosimetric parameters. A tumor volume enlargement of ?10% in GTVnx or GTVnd after induction chemotherapy has no significant impact on the dosimetric parameters of subsequent radiotherapy in locally advanced NPC.Suicide is one of the top 20 leading causes of death worldwide. With the rapid spreading of coronavirus disease 2019 (COVID-19) crisis around the world, suicide cases induced by the COVID-19 pandemic have been reported in many countries. Individuals with suspected and confirmed COVID-19 infection, frontline healthcare workers, bereaved families, elders, children, and adolescents are vulnerable populations who might be at elevated suicide risk. In this micro-review, a systematic search through PubMed was performed for a comprehensive investigation of suicide risk factors during the pandemic. On this basis, we put forward considerations and advice for preventing pandemic related suicide, including staying socially connected through online platform or apps during period of quarantine, reducing unemployment, dispelling rumors and misinformation in time, and maintaining evidenced-based management of psychiatric symptoms. More importantly, early detection and timely intervention of individuals with psychiatric disorders and suicide behaviors will be effective to reduce the number of suicides, with specific measurements of using validated scales to perform regular suicide risk screening, improving the availability of mental health services, and providing appropriate and evidence-based interventions for individuals in demand. Policy makers, psychiatrists, psychologists, and other healthcare professionals need to collaborate to control the possible suicide events during the COVID-19 pandemic and future possible crisis.Functional decline of stem cell transplantation in ageing hosts is well documented. The mechanism for this is poorly understood, although it is known that advancing age does not provide an optimal milieu for exogenous stem cells to survive, engraft and differentiate. We showed that n-butylidenephthalide improved human adipose-derived stem cell (hADSC) engraftment via attenuating the production of reactive oxygen species (ROS). It remained unclear whether pre-treated hosts with n-butylidenephthalide can rejuvenate the ageing heart and improve hADSC engraftment by regulating the ROS/NLRP3 inflammasome-mediated cardiac fibrosis after myocardial infarction. One hour after coronary ligation, hADSCs were transplanted into the hearts of young and ageing Wistar rats that were pre-treated with or without n-butylidenephthalide for 3 days. At day 3 after infarction, myocardial infarction was associated with an increase in ROS levels and NLRP3 inflammasome activity with age. hADSC transplant effectively provided a significant decrease in ROS levels, NLRP3 inflammasome activity, IL-1β levels and cardiac fibrosis in either young or old infarcted rats. However, the beneficial effects of hADSCs were greater in young compared with old rats in terms of NLRP3 inflammasome activity. The infarcted ageing rats pre-conditioned by n-butylidenephthalide improved engraftment and differentiation of hADSCs and additionally attenuated cardiac fibrosis compared with hADSCs alone. The anti-inflammation effects of n-butylidenephthalide were reversed by SIN-1. https://www.selleckchem.com/products/ws6.html In conclusions, the increased NLRP3 inflammasome activity plays the pathogenesis of ageing-related functional hADSC decline in the ageing hosts. n-butylidenephthalide-pre-treated ageing hosts reversibly ameliorate the harsh microenvironments, improve stem cell engraftment and attenuate cardiac fibrosis after myocardial infarction.Cancer-specific death (CSD) and non-cancer-specific death (non-CSD) after stereotactic body radiotherapy (SBRT) for pulmonary oligometastases have not been studied in detail. The aim of this study was to determine the cumulative incidences of CSD and non-CSD and to reveal prognostic factors. Data from a large survey of SBRT for pulmonary oligometastases were used for analyses, and patients with unknown cause of death were excluded from current analyses. CSD was primary cancer death and non-CSD was non-primary cancer death including a series of cancer treatment-related deaths. Cumulative incidences were calculated using the Kaplan-Meier method and a stratified Cox regression model was used for multivariate analyses (MVA). Fifty-two patients with an unknown death were excluded and a total of 1326 patients was selected. CSD and non-CSD occurred in 375 and 109 patients, respectively. The median OS period was 53.2 months and the cumulative incidences of 1-, 3-, and 5-year CSD vs. non-CSD rates were 6.5% vs. 2.3%, 29.5% vs. 8.6%, and 41.2% vs. 11.0%, respectively. In MVA, the incidence of CSD was related to performance status (1 vs. 0; p less then 0.001, 2-3 vs. 0; p = 0.011), oligometastatic state (sync-oligometastases vs. oligo-recurrence, p = 0.026) and maximum tumor diameter (p = 0.009), and the incidence of non-CSD was related to age (p = 0.001), sex (p = 0.030), performance status (2-3 vs. 0; p = 0.002), and irradiated tumor-located lung lobe (left lower lobe vs. other lobes, p = 0.036). CSD was main cause of death, but non-CSD was not rare after SBRT. Prognostic factors for CSD and non-CSD were different, and an understanding of the factors would help in treatment.Neuromyelitis optica spectrum disorder (NMOSD) is a type of central nervous system antibody-mediated disease which affects mainly optic nerves and spinal cord, but may also present with acute brainstem syndrome, acute diencephalic syndrome, and cerebral syndrome with typical brain lesions. One of the most disabling symptoms, diagnosed in 29%-67% of cases, is cognitive dysfunction, with such processes as memory, processing speed, executive function, attention, and verbal fluency being predominantly affected. However, description of cognition in NMOSD patients is still a relatively new area of research.
A systematic MEDLINE search was performed to retrieve all studies that investigated cognitive impairment and its clinical correlates in patients with NMOSD.
We summarize the current knowledge on cognitive impairment profile, neuropsychological tests used to examine NMOSD patients, clinical and demographical variables affecting cognition, and magnetic resonance imaging correlates. We provide a comparison of cognitive profile of patients with multiple sclerosis and NMOSD.
